Only 12 weeks?! You are one lucky customer.
I finally decided to take my 1st Chanel (now vintage) in for refurbishment on the outside. This shoulder bag which I purchased long long time ago was in mint condition as I hardly use it, but the lamb skin color has turned sort of brownish instead of jet black, I always kept it in the dust bag and wonder why it was like that, my other lamb skin m/l started to fade as well....
SA told me it takes "few" months and asked me to check back in 6 months if I don't hear from them.... I was going to wait to see how they do on the refurbish before turning in my m/l, I think I might need to just give it to them as it seems taking longer and longer for Chanel to do these type of refurbishment.
